Application ctober 7, 1953, Serial No. 384,723

3 Claims. (Cl. 132-42) This invention relates to a hair curling rod of the extensible type wherein the rod is split longitudinally and provided with means for expanding the rod as hair is wrapped thereon and in which the expanding means is relieved so that the rod contracts with the hair thereon to relieve tension in the hair as hair wound tightly on a rod impedes the penetration of the permanent waving and neutralizing solution, and in particular this invention includes cams positioned in both ends of a longitudinally split hair curling rod in which both cams are mounted on the same shaft and are adapted to be operated by knobs on the ends of the shaft.

The purpose of this invention is to provide an improved hair curling rod wherein both ends of the rod are spread and contracted simultaneously and wherein the spreading and contracting means is adapted to be actuated from either end of the rod.

This invention is an improvement over the cold permanent wave rod of my co-pending application filed April 6, 1953 with the Serial No. 347,060 in that whereas the rod of the co-pending application is spread with one cam at the center, the rod of this application is spread with earns at both of the ends and the cams are mounted to spread both ends simultaneously.

The object of this invention is, therefore, to provide a longitudinally split hair curling rod in which spreading means are provided in both ends of the rod and in which the spreading means in the ends of the rod are adapted to be actuated simultaneously by a knob at one of the ends of the rod.

Another object of the invention is to provide a longitudinally split hair curling rod that is adapted to be actuated with either a rotating or sliding action of spreading means within the rod.

A further object of the invention is to provide an improved longitudinally split hair curling rod having expanding means therein in which the rod is of a simple and economical construction.

With these and other objects and advantages in View the invention embodies a hair curling rod formed with two semi-circular sections, with resilient means for holding the sections together and with spreading means extended through the rod and adapted to be actuated by a longitudinally disposed shaft extended through the rod.

Other features and advantages of the invention will appear from the following description taken in connection with drawings, wherein:

Referring now to the drawings wherein like reference characters denote corresponding parts the improved hair curling rod of this invention includes a section lil, substantially semi-circular in cross section, a section 11, similar to the section 10, a shaft 12 extended longitudinally through the rod and having cams 13 and 14 thereon and elastic bands 15 and 16 for resiliently urging the sections 1l) and 11 against the cams 13 and 14, respectively. The shaft 12 is provided with a head 17 on one end and a knob 18 having slots 19 therethrough on the other and with the shaft in the position shown in Fig. 3 the cams 13 and 14 are in engagement with cam surfaces 20 and 21 on the inner surface of the section 10 and 22 and 23 on the inner surface of the section 11.

The semi-circular sections lil and 11 are provided with enlarged ends and the intermediate portions are formed with concave surfaces providing a rod with a comparatively small central portion.

As shown in Figures 2 and 3 one end of the section 11B is provided with a plate 24 having a slot 25 therein and the end of the shaft 12 on which the head 17 is positioned, and which extends through the slot, is provided with a shoulder 26 which abuts the outer surface of the plate 24. A pin 27 which forms the end of the shaft 12 extends from the shoulder 26, providing means for holding an eye 2S of a strap 29, preferably of elastic material.

The strap 29 is mounted on the opposite end of the rod with an eye 30 that is positioned in a groove 31 formed by a disc 32 on the end of the section 11.

The knob 18, which is positioned on the end of the shaft opposite to that on which the head is carried, extends through a slot 33 in the disc 32, and the outer surface of the knob is provided with a split stern 34 having a ridge 35 on the outer end. The stem 34 is adapted to receive the eye 30 of the strap 29 whereby the strap may be, selectively, mounted in the groove 31 or on the stem 34 of the shaft as may be desired.

The bands 1S and 16 which are of elastic or spring material are positioned in semi-circular slots in the sections, the section having semi-circular grooves 36 and 37 for receiving portions of the band therein and the section 11 having complementary semi-circular grooves 3S and 39 therein.

The section 10 is provided with perforations 40 and similar perforations are provided in the section 11, as indicated by the numeral 41. The perforations allow the lotion to pass through the rod to make a faster process. The outer surface of the section 10 is also provided with serrations or teeth 42 which facilitate gripping the ends of hair on the outer surface of the rod in starting a curl.

The inner portion of the section 10 is provided with recesses 43 and 44 that are positioned to receive the cams 13 and 14 and similar recesses 45 and 46 are provided in the section 11 whereby with the cams moved longitudinally into the recesses the sections are moved together by the elastic bands.

In starting a curl on the rod illustrated in Figs. l to 6 inclusive the eye 34 of the strap 28 is removed from the head on the end of the shaft 12 and the shaft is moved to the position shown in Fig. 4 by knob 18 whereby the cams 13 and 14 separate the sections 10 and 11 to expand Ithe rod. With the rod in the expanded position ends of hair for a curl are held against the teeth 42 and the rod is rotated toward the head with the hair being wrapped tightly thereon. Upon engagement of the rod with the head the eye 34 of the strap 23 is snapped over the end of the rod and by pressing inwardly on the knob 18 sections of the rod are contracted, thereby relieving the tension of the hair wrapped on the rod.

In the design illustrated in Figs. 7 to ll, inclusive, the rod is formed with sections 50 and 51, substantially semicircular in cross section with an end wall 52 extended from the section S9 over the end of the section 51 and with an end wall 53 extending from the section 51 over the end of the section Sil and the sections are resiliently held together with elastic bands 54 and 55.

In this design the sections are expanded by cams 56 and 57 on a shaft 58 and with the shaft rotated by knobs 59 and 60 positioned on the ends thereof. With the cams formed as illustrated in Figs. 9 and l0 the cams coact with cam surfaces 61 in the Sections 50 and 62 in the section 51 and as the cams are moved from the positions shown in Fig. 9 to the positions shown i'n Fig. lO the sections of the rod are expanded.

The shaft 5S extends through an opening 63 in the plate 52 and also through an opening 64 in the plate 53 and, as illustrated in Fig. 8 the elastic bands are positioned in semi-circular grooves 65 and 66 in the section 5@ and 67 and 68 in the section 51. The section 50 is also provided with teeth 69, similar to the teeth 42.

In this design hair is retained on the rod with a cord or strap 70, one end of which is positioned in a recess 71 at the end of an opening '72 in the knob 6i) and the other adapted to be extended through slots 73 and 74 in the knob 59. The cord or strap 70 is provided with an enlarged end 75 by which the cord may be gripped by a thumb and foreiinger so that it may be stretched and inserted in the slots 73 and 74.

In the design illustrated in Figs. l2 to 16, inclusive the rod is formed with sections 76 and 77 and the sections, which are resiliently held with elastic bands 78 and 79 are expanded by cams S0 and S1 on a shaft S2, the ends of the shaft being provided with knobs 83 and 84.

With the cams formed as illustrated in Figs. 14, l5, and 16 the sections of the rod may be expanded by either rotating the shaft or by sliding the shaft longitudinally in the rod.

The section 76 is formed with recesses 85 and S6 that 75 are positioned to receive the cams Sil and 81 and corresponding recesses 87 and 88 are provided in the section 77. With the cams positioned in the recesses the sections are spread by rotating the shaft and when the shaft is moved longitudinally the cams Sil and 31 engage cam surfaces 89 and 90 in the section '76 and 91 and 92 in the section 77, to spread the rod.

Also in this design the section 76 is provided with a head 93 having an annular groove 94 therein and the section 77 is provided with a similar head 95 having an annular groove 96 therein. The shaft 82 extends through a slot 97 in the head 93 and also through a slot 98 in the head 95. The outer surfaces of the knobs S3 and 84 are provided with slots 99 and 109, respectively through which the ends of the elastic strap or cord may be placed for securing hair on the rod.

With the improved expanding hair curling rod of this invention formed in either of the designs shown the rod is applied to groups of strands of hair, preferably with the hair slightly wet and with the ends of the strands of hair placed on the teeth of one section of the rod, the rod is rolled toward the scalp binding the hair tightly thereon with the rod in the open or expanded position. Upon reaching a position against the scalp a strap, cord, or other means secured to a knob or head at one end of the rod is extended over the hair on the rod with the opposite end secured in a knob or head on the opposite end of the rod. With the hair secured on the rod in this manner the cams are actuated to release the sections whereby the elastic bands or springs contract the rod relieving tension in the hair.

With the tension relieved in the hair on the rod the lotion is applied to the hair and as the hair is not tight the lotion penetrates the areas between and around the strands of hair thereby coming in contact with substantially all strands and consequently activating the process.

Although this expanding hair curling rod is particularly adapted for professional use in beauty shops it is also adapted for individual use in doing a home permanent. This improved curling rod is also particularly adapted for hair curling and for cold permanent hair waving.

It will be understood that although the sections forming the body of the curler or hair curling rod are shown comparatively solid the walls of the sections may be made of dilerent material such as sheet metal, wood, plastic, die-castings or the like.

This improved hair curling rod is of the type especially adapted to be used for more efficiently and eectively curling the hair, to provide better and softer curls and reducing the dryness of the hair.

It will also be understood that other modifications, within the scope of the appended claims, may be made in the design and arrangement of the parts without departing from the spirit of the invention.
